T0 @ZZ whom t may concern:

Be it known that I, WILLIAM L. TUCKER, a citizen of the UnitedBridgeport, in the county of Caddo and Territory of Oklahoma, haveinvented new and useful Improvements in Oultivators, of which thefollowing is a specification.

My invention relates to improvements in cultivators.

It relates particularly to riding-cultivators in which the driveremploys his'feet for swinging the beams laterally. In such cultivatorsit is comparatively easy for the driver to force the beams outwardly,but more diflicult for him to draw the beams toward each other with hisfeet.

The object of this invention is to provide means by which the driver mayeasily swing the beamsapart, means being provided by which the beams areretracted toward each other.

` In its preferable form my invention provides a resilient archconnecting the two beams, the tension of the arch normally forcing thebeams laterally to a certain position, which certain position is the onein which the beams are most commonly used.

My invention provides, further, rear carrywith means by which the driverwith his feet may laterally swing the carrying-wheels', and thuslaterally swing the beams.

Another obj ect of my invention is to provide a novel form of archcombined with means by which the axles pivoted in the arch may be swungso as to swing the forward wheels.

Another object of my invention is to provide in combination with thelaterally-swinging beams a third beam having thereon a cutting blade orshovel and connected by a uni-l versal joint with the arch and meanssupported by the swinging beams for vertically and laterally oscillatingthe third beam.

My invention provides means, further, lby

which the cultivatoreshovels maybe withdrawn from the ground with aminimum amount of force.

Other novel features are hereinafter fully described and claimed. A

Fig. 11 is a sideelevation view of the intermediate shovel-beam and the lever foroperatin it. Fig. l2 is a rear elevation view of theIever for operatingthe intermediate shovel-beam and some of the parts connected therewith.

Similar characters of reference denote similar parts.

1 denotes the forward carrying-wheels rotatively mounted, respectively,upon the horizontal portions of the axles 2, each of which is providedwith a vertical portion pivotally mounted in the arch. The archcomprises, preferably, two parts laterally adjustable toward and fromeach other and provided with means forsecuring the two parts of thedivided arch in the positions to which they may be adjusted.

In its preferable .form myy invention provides two vertical tubularmembers 3, in which the vertical portions of the axles 2 are pivotallymounted, respectively, said axles 2 ICO having each a collar 4, uponwhich rests the y lower end of the adjacent tubular member 3.

' The vertical portions 'of the axles 2 have their upper ends projectingabove the members 3 and have secured thereto, respectively, the twocrank-arms 5. Each member 3 is provided with a horizontal, preferablyrectangular, portion 6, which extends towardy and is adjustable towardand from the opposite horizontal portion 6. 7 and 8, disposed,respectively, in front and Two clamping-plates j IIO at the rear ofthehorizontal portions 6, are secured thereto by transverse bolts 9,extending therethrough and located in transverse holes provided thereforin the horizontal portion 6. The portions 6 and the plates 7 and 8 areprovided, preferably, with a series of transverse holes by which thehorizontal portion 6 may be adjustably mounted' between theclamping-plates 7 and 8 relative toV each other. When it is desired towiden the arch, the bolts 9 are Withdrawn and the members 3 movedoutward laterally to the position desired, at which time the bolts 9 areinserted in the transverse holes in the portions 6, suitably located forretaining the parts in the positions to which they have been adjusted.The rear plate 8 is preferably of angle-ironvand has secured to itpivotally the forward end of a horizontal lever 10. Two horizontal bars11 are pivotally connected at one set of ends, respectively, to thecrankarms 5, the other set of ends being provided with a series ofvertical holes 12, through each of which may be inserted a vertical bolt13, extending through a hole provided therefor in the lever 1() and bymeans of which the bars 11 are connected pivotally to the lever 10. Bychanging the bolt 13 from one hole 12 to the other in each of the bars11 the normal position vof the crank-arm 5 relative to the arch may bevaried. By laterally swinging the lever 10 the wheels 1 may be swungsimultaneously in like directions through the intermediacy of the bars11, crank-arms 5,

and axles 2. For retaining the lever 10 in the position to which it maybe adjusted a locking mechanism is provided, comprising the followingparts: Slidable longitudinally on the lever 10 is a sleeve 14, providedat its forward end witha projection 15, adapted to enter one or moreperipheral notches 16 on a horizontal ratchet-plate 17, the forward endof which is secured to the angle-iron 8 'by means of two vertical bolts18 extending through said ratchet-plate and the horizontal portion ofsaid angle-iron. The sleeve 14 is withdrawn from engagement with theratchet-plate 17 by means of a horizontal rod 19, the forward end ofwhich is connected to the sleeve 14 and the rear end of which isconnected to one arm of a bell-crank lever 20, pivoted at its angle bymeans of a vertical bolt 21 to the member 10. A coil-spring 22,

encircling the rod 19, has its rear end bearing tions, respectively, ofthe axles 2.

upon a plate 23, secured to the lever 10, and its forward end bearingagainst the rear end of the sleeve 14. Two horizontal shovelbeams 24 and25 are pivotally mounted adj acent their forward end upon the verticalpor- Two vertical shafts or wheel-supports are pivotally mounted one inthe rear end of each beam 24 and 25. Each shaft 26 is provided above theadjacent beam with a forwardly-extending 'arm 27, to the outer end ofwhich is connectved a strap 28, by which the arm is secured to theadjacent foot of the driver. Each shaft or wheel-support 26 below theadjacent beam has a rearwardly-extending arm 29, provided with ahorizontal lateral projection 30, upon which is rotatively mounted acarrying-wheel 31. The carrying-wheels 31 are preferably dished, onconcave inner sides of each of which is secured a collar 32 by means ofbolts 33, which extend through holes provided in the collar and thescrew-threaded ends of which are fitted in the screw-threaded holesprovided transversely in the adjacent wheel 31. Each collar 32 isprovided with a central horizontal hole fitted to the projection 30,which projection -is screw-threaded at its outer end and has mountedthereon a nut 34, located in a central recess .provided in the outerside of the washer 32. This manner of mounting the wheels 31 preventsthe access of dirt and moisture to the bearings. Each shaft orwheel-support 26 is provided at its upper end with arearwardly-extending horizontal arm 36. A transverse horizontal bar 37,preferably of resilient material, is supported at its respective ends bythe arms 36. Below the arms 36 on the shafts 26 are pro vided tworearwardly-extending horizontal arms 33. Two vertical rods 39 have theirupper and lower ends secured, respectively, to the adjacent arms 36 and38,. Encircling said rods 39 are two coil-springs 40, mounted one oneach rod and the lower end of each of which is supported by the adjacentarm 33. A transverse bar 41 is provided at its ends, respectively, withvertical holes, in which are slidably fitted the rods 39. The ends ofthe .bar 41 are supported upon the upper ends of the springs 40,respectively. The bars 37 and 41 support centrally thereon the driversseat 42, which seat rests upon the upper bar 37, said b ar resting atits middle upon the upwardly-turned middle portion of the bar 41.

The driver when mounted on the seat 42 has his feet secured to the arms27 by the straps 28. He can thus force the arms 27 outwardly, thusswinging the shafts 26 so as to swing the forward parts of the wheels 31in an outward direction, thus causing the beams 24`and 25 to be swunglapart from each other at their rear ends. @wing to physical reasons, itis more diflicult for the driver to swing the beams 24 and 25 towardeach other than it is for him to push them apart. To assist the driverin swinging the beams inwardly at their rear end, I provide a resilientmeans which normally tends to force the beams laterally to and retainthem in a certain position, which position is the one in which it isdesired to retain them the greater portion of the time. This resilientmeans comprises the following elements: a resilient arch, comprising twoupwardly-extending inwardly-curved resilient rods 43 and threeclamping-plates 44 and 45, has its ends se- IOO cured, respectively, tothe beams 24 and 25. The beams 24 and 25 are provided each with avertical hole in which is inserted the lower end of the adjacent rod 43.Each of said rods 43 is provided with one or more coils 46, wlichservesto increase the fiexibility of the ro s. rods 43 are held clampedbetween two rear plates 44 and a forward plate 45, connected to the rearplates 44 by means of two bolts 47, which extend through horizontalholes provided in the plates 44, respectively, and between the rods 43,the forward ends of the bolts 47 being screw-threaded and fitted to Iscrew-threaded holes provided therefor in the plate 45. By loosening thebolts 47 the rods 43 may be adjusted lengthwise relative to each otherfor widening or narrowing the resilient arch, and thus providing meansfor varying the normal position of the beams 24 and 25.. When the driverVdesires to throw apart the rear end of the beams 24 and 25 with hisfeet, he forces outwardly the arms 27, thus swinging apart the rear endsof the beams 24 and 25, as already described, and against the pressureof the rods 43, which rods, when the outward pressure upon the arms 27is removed, retract the bars 24 and inwardly to their normal position. Y

Upon each beam 24 and 25 is mounted a .gang of shovels 48. Each gang ofshovels is provided with two beams 49, having secured to their rearlowerends the shovels 48 and pivotj ed adjacent its forward end to theadjacent 3 5 beam 24 or 25, as the case may be, by means of a horizontalbolt 50. Each beam 49 has a portion extending in front of the adjacentbolt 50, which is embraced upon its upper and lower sides by abifu-rcated rearwardly- 4o extending arm 51, two of which are providedat the lower end of each of two upwardly-extending levers 52, each lever52 having a bifurcated lower end pivotally mounted upon a horizontalbolt 53, located in a transverse hole provided one in each beam 24 and25. When the levers 52 are swung forward and backward, the beams 49 areswung so as to throw the shovels 48 downward and upward, so that theymay be inserted into or withdrawn from the ground. For releasablylocking the levers in any desired position, two curved ratchet-plates 54are secured upon the upper sides, respectively, of the beams 24 and 25.Each ratchet-plate 54 is `located between the arms of the bifurcatedlower end of the adjacent lever 52 and is provided with a series ofradial holes 55, each adapted to receive therein a bolt 56, slidablymounted lengthwise of the adjacent lever 52 in suitable openingsprovided in the two laterally-extending arms of i a U-shaped plate 57,which connects the two arms of the adjacent lever 52. Each bolt 56 isencircled by a spring 58, which encircles 65 the bolt and has its lowerend bearing upon The upper horizontal portions of the the flange 59 andthe upper end against the lower side ofthe upper arm of the plate 57.For withdrawing the bo'lt 56 from the opening 55 in which it is located,so that the adjacent lever 52 may be swung to a different position, thefollowing mechanism is provided To the upper end of each bolt 56 issecured the lower end of a rod 60, the upper end of which isecured toone arm of a bell-cranklever 61, pivoted to the-upper end of theadjacent lever 52. By properly swinging the bell-crank levers 61 thebolts 56 may be withdrawn against the pressure of the springs 58 fromengagement with the ratchet-plates 54, thus permittingswinging of thelevers 52 forward and backward.

For the purpose of cutting out grass and weeds when cultivating corn andfor thinning out cotton when the cultivator is used for cultivatingcotton l provide a shovel-beam located between the beams 24 and 25 andprovided with means by which the driver may vertically and laterallyoscillate said beams. A beam 62 has secured to its lower vertical end ashovel 63, the forward horizontal end of the beam 6 2 being connected,by means of a universal joint, with the forward arch in a manner suchthat the said beam may be swung vertically and laterally.

.he universal joint comprises the followingdescribed mechanism: Avertical plate 64 l has its upper end secured rigidly to the forwardside of the arch by means of a horizontal plate 65 and two bolts 66,which extend through openings provided therefor in the plates 7 8 65 andhorizontal portions 6, the

bolts being located at each side, respectively, of the plate 64.

The forward ends of the bolts 66 are. screwthreaded and have mountedthereon the nuts 66, which retain the plate 65 against the plate 64. Thelower end of the plate 64 is U-shaped and provided throughthe two armswith transverse holes in which is rotatively mounted a horizontallongitudinally-disposed bolt 68, the rear end of which is provided witha transverse hole in which is rotatively mounted a horizontal bolt 69,which extends through holes provided for it in the arms of thebifurcated forward end of the beam 62.

The forward end of the bolt 68 is threaded and has mounted thereon a nut,70, which bears upon the forward side of the plate 64.

Pivoted at it-s lower end by means of a horizontal bolt 71 to the rearpart of the beam 62 is a lever 72, disposed vertically and provided witha longitudinal slot 73, in which is mounted a pin 74, having its rearend rigidly secured to the plate 45 and which serves as a fulcrum forswinging the levers 73 to and fro for laterally oscillating the beam 62and shovel 63. The upper end of the lever 72 is provided with arearwardly-curved handle 75, by which the lever is laterally oscillatedand raised and lowered. lFor exerting a lifttion of my l swinging ingpressure upon the rear end of the beam 62 a coil-spring 75 is provided',the upper end of which is secured to the plate 45 and the lower end ofwhich is connected to the vertical portion of the beam 62, the tensionof the spring being such that it will have a lifting effect upon thebeam. In operating this porinvention the driver occupying the seat 42may, with one hand grasping the handle 75, swing the lever 72 laterally,so as to swing the shovel 63 to the place desired. He can when desiredto lift the shovel 63 clear of the ground effect this result by drawingthe lever 72- upwardly.
